This standard was published in 1998. The experience this revision. The major changes in this revision are: a) Lateral filing cabinet is added. b) Ratings of 180 min and 240 min have been added. c) Restriction on size has been removed. d) Telescopic suspension system is also added for drawers. gained in implementation of this standard has necessitated Security equipment play a vital role in the safe custody of cash, jewellery, important documents, etc, in various establishments such as banks, hotels, commercial organizations, shops, etc. A number of standards had been formulated on security equipments. This standard on fire resisting (insulating) filing cabinets is one such standard. Record protection cabinets and filing cabinets are generally used to insulate the paper media against fire only. Record protection cabinets (see IS 14203:1999 `Fire resisting record protection cabinets -- Specification') are used for protect ion of ledgers, account books, legal documents, etc. The insulating filing cabinets covered by this standard are generally used to protect the vital information and records/documents stored in the form of files. These cab inets may be kept either in strong rooms/book rooms for added protection against theft and fire or maybe kept in open halls. The composition of the Committee responsible for the formulation of this standard is given in Annex C. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2:1960 `Rules for rounding off numerical values (revised)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
